It's somewhat troubling to know that Rosenfels is now a play away from running the Dolphins offense, and this is no knock on his ability. But the Dolphins have championship aspirations, and it might be asking a lot of someone so green to step into the spotlight like that.
But the Dolphins are confident Rosenfels could get the job done should anything happen to Lucas while Fiedler is sidelined, which will be at least a month.
"Sage has been with us now for five or six weeks and he has a good grasp of the offense," said Coach Dave Wannstedt. "He will go in as the No. 2 quarterback."
That issue settled, the Dolphins also need to bring in somebody else at the position because they need someone to take some of the practice reps and also to run the scout team, a job formerly performed by Rosenfels.
The Dolphins have been busy trying to determine who is available and who should be brought in, but we can tell you it won't be Tim Levcik or Zak Kustok, the two rookie free agents who were in camp this summer.
"How much (the new quarterback) would be in the plans as a possible player, that wouldn't be a priority at this point as much as bringing someone else in that can throw, so you are not overworking the guys," Wannstedt said. "Now that Sage is going to have to be involved in the game plan, he is not going to be able to do all the practice and the scout team work.
"Rick (Spielman), Norv (Turner) and Mike Shula and I are going through some names and we will bring some guys in."
As mentioned before, the Dolphins expect Fiedler to be out at least a month, but his absence possibly could be longer.
As much as he felt bad for the guy, Wannstedt marveled at the fact Fiedler finished the game with a broken thumb.
"If anyone needed additional information to reaffirm the type of winner that Jay Fiedler is and what he is willing to sacrifice and do to give this team a chance to win, this is just another example of that," Wannstedt said. "He didn't want to come out. I was standing there with (head trainer Kevin O'Neill) when he was throwing passes on the sideline to Ray. They were talking about it and he wanted to see this thing through. He did that."
